Last year, she tackled sci-fi ("Ender's Game) and Shakespearean tragedy ("Romeo and Juliet"). And the 17-year-old high school junior has a cluster of films completed, including "3 Days to Kill," which opens Feb. 21. Penned by Luc Besson and Adi Hasak and directed by McG, the spy thriller-drama finds Steinfeld playing Zoey, the estranged teenage daughter of a dying CIA assassin (Kevin Costner).

Also in the pipeline for the actress, who lives with her family in Thousand Oaks, are the Toronto Film Festival fave "Can a Song Save Your Life?," Tommy Lee Jones' "The Homesman" and the action-comedy "Barely Lethal" — in this one, she's the assassin.

That was one of my favorite scenes in the movie. We had a great, great time. Kevin and McG worked with me in creating something really special.

You also just worked with Tommy Lee Jones, who not only stars in but also directs "The Homesman."

That is a period piece. I don't know if it is sort of classified as a western, but I play a very, very, small part in it. I will say I don't think I have ever been more nervous in my life as I was when I was doing one scene with Tommy Lee Jones. I had like three lines and they wouldn't come out of my mouth. I get nervous about pretty much everything.

Really? Even when you were just 14 and going through the Academy Awards three years ago, you seemed unflappable.

The thing I find as I get older that I think, maybe, I get more nervous because I have become aware of what is actually happening.

When I was 13 and shooting "True Grit" and when I was at the Oscars, I had no idea what I was getting myself into. It took me a very long time to realize just how incredibly special that entire time in my life was. I enjoyed every single minute. But I would do anything to sort of relive it. But I have been so fortunate to have had amazing experiences since then.

You're a home-schooled high school junior. Are you thinking about college?

Last year, I was thinking about it nonstop. The norm is that you go after you graduate from high school. I don't know where in the world I will be next week and I don't know where I will be in a year, so I was sort of worked up over that. I had conversations with my parents and my teachers. That brought to my realization that college is always there. That is a comforting feeling. I hope that I can find a good time to do that.
